[Nook Color General] GMPOWER:
I was able to spend some time today looking into the issue, I did not get very far. Your build.prop file has all the needed changes to it, so no problem there. Updating the Market was the only thing that had worked for me to get the Market going again. This is a copy of the logcat of the error

A google search of the error shows that a lot of android users have had this problem, some with brand new device. It appears that most people’s only way of fixing the issue is to update the Market or starting over.

You might want to try to install the new market again, but first clear data/cache and force stop Market before you attempt to reinstall the new one. I will continue to look into the problem, but it might be faster for you to try to install the updated Market on your May backup or start over.
